Customer Testimonials
We are very pleased with the beautiful front door and double glazed windows provided by Kayvex Windows. We now have fewer draughts and less noise from outside. Kayvex replaced our back patio door a few years ago, and John provided a very competitive and totally unpressured quote this time too. All of the staff were very helpful and professional and our fitters were very tidy and finished off everything even when it rained. It was also reassuring to be able to visit the showroom in Littlehampton. The door opens, closes and locks very smoothly and the letterbox is very well sealed. We particularly wanted small upper windows to open, Kayvex are able to provide lots of varying layouts.
We are very happy to recommend Kayvex Windows and are glad to be able to support a local business.

Excellent customer service from start to finish from Kayvex, John was very helpful on the first visit and gave very good advice. We were kept updated via email and phone call from the office staff throughout the whole order process and installation.
On installation day the fitter arrived on time, was very friendly and advised on maintenance after job was completed, also very clean and tidy.
I would thoroughly recommend Kayvex for whatever project you are planning.
